Good Jazz

I want to buy some good jazz albums but don't know where to start. What are some good "must-have" Jazz albums. I'm open to anything, new, old, anything. I just want to experiance new music. Thanks for your time.

No one here has mentioned Michael Brecker or Joe Pass. Two amazing musicians that no one interested in jazz should overlook. Charlie Parker is also a very good pick. Without a doubt though you should look into the miles davis quintet.
